Description
Technical field
The utility model belongs to vibration damper surveying instrument technical field, relates to vibration damper bottom valve seat valve line measuring instrument specifically.
Background technology
Foot valve seat is one of vital part of vibration damper, wherein, detects whether ring 9, outer shroud 8 valve line differences in height and flatness meet design requirement particularly important in the foot valve seat shown in Fig. 2,3.The measurer of ring 9, outer shroud 8 valve line differences in height and flatness is dial gauge 10, clearance gauge in traditional measurement foot valve seat, measurement.Measure the measurement point that is positioned on ring 9, the outer shroud 8 same diameter lines with dial gauge 10 as shown in Figure 5, calculate this diameter line upper inner ring 9, outer shroud 8 valve line differences in height, mobile then indicator bracket, measure interior ring 9, outer shroud 8 valve line height on the different-diameter, measure several points with the method, find out the maximal value and the minimum value of the inside and outside valve line difference in height of this tested part.
Because the inner and outer rings valve line plane width of most foot valve seats is narrower, and difference in height is also very little, so the difficult measurement of operator, checkability is low, and measurement data is also inaccurate.The measured foot valve seat inner and outer ring valve line difference in height of this method and the measurer of flatness have been carried out measurement System Analysis, its R﹠amp; The R value is respectively 43.2% and 57.31%, and the Repeatability and Reproducibility of measurer is considerably beyond 10%, and measuring system exists than mistake, thereby may produce wrong judgement to this size.
The utility model content
The purpose of this utility model has provided a kind of vibration damper bottom valve seat valve line measuring instrument that can more accurately detect foot valve seat inner and outer rings valve line difference in height and flatness.
The technical solution of the utility model is as follows:
Vibration damper bottom valve seat valve line measuring instrument, this measuring instrument comprises that the lower surface of clock gauge, gauge stand, described gauge stand has reference rings, the center of this reference rings is provided with register pin, have the clock gauge mounting hole on the vertical direction of described gauge stand, a wherein openend of this clock gauge mounting hole is positioned at the ring of described reference rings, by described clock gauge mounting hole clock gauge is installed on the described gauge stand, the gauge head of wherein said clock gauge stretches out outside the determined surface level of described reference rings.
Adopt said structure, described reference rings diameter is identical with outer ring surface valve linear diameter, and reference rings is close to outer shroud during measurement, and the clock gauge gauge head is identical with inner ring surface valve line radius apart from the distance at reference rings center, and the clock gauge gauge head contacts with inner ring surface valve line during measurement.Rotate tested one week of foot valve seat (360 °), it is poor that then the maximum of the side-play amount of clock gauge pointer, minimum value then are respectively maximum, the minimum constructive height of the inside and outside anchor ring valve line of tested foot valve seat, difference in height mean value=(minimum value of the maximal value of clock gauge pointer offset+clock gauge pointer offset) ÷ 2.Before above-mentioned measurement, need this measuring instrument is carried out zero, promptly earlier measurer is placed on calibrated bolck colonel zero and gets final product.
Have the clock gauge pilot hole on the sidewall of described gauge stand, this clock gauge pilot hole is rotary with bolt.
The radius of described reference rings is 14-15mm.The centre distance of the described reference rings of openend centre distance of described clock gauge mounting hole is 9-10mm
Beneficial effect: this measuring instrument is simple in structure, and the measuring accuracy height is compared with the traditional detection measurer, and following advantage is arranged:
1, can fast detecting product, thereby the factory inspection of going into that both can be used for part receives, and also can be used for 100% check of production scene.
2, easy to operate, the Repeatability and Reproducibility of measurer is better, the R﹠amp of height-gauge measurement System Analysis; R reaches 8.98%, the R﹠amp of flatness measuring instrument measurement System Analysis; R is 9.13%, can satisfy client and request for utilization.
3, according to this mentality of designing, change outer ring surface valve line reference field and inner ring surface valve line probe location size, can design piston, the bottom valve seat valve line measuring instrument of various models.
